Job description

We believe “It’s all about the user. All of them.” We’re passionate about providing a seamless one-stop experience for business travelers, no matter how they travel, where they stay, or where they’re going. We are looking for a Sr. Full-Stack Engineer to lead the design and development of mission-critical product features and services that power our platform, used daily by thousands of travelers worldwide. You will play a pivotal role in shaping technical direction, mentoring engineers, and driving cross-team initiatives to deliver scalable, reliable, and user-focused solutions. What You’ll Do • Lead technical strategy and architecture for core backend and frontend components of the platform, ensuring scalability, reliability, and performance. • Own complex domains end-to-end: from design through development, launch, and ongoing evolution of key microservices and customer-facing features. • Influence cross-functional teams (engineering, product, design) by aligning technical execution with business goals and long-term product vision. • Raise the technical bar through code reviews, architectural guidance, and fostering best practices in testing, monitoring, and documentation. • Mentor and coach engineers across the organization, helping to grow technical skills and leadership capabilities. • Partner with leadership to define and execute a multi-year technical roadmap, ensuring that platform investments support company growth at scale. What We’re Looking For • 5+ years of software development experience, with deep expertise in both backend and frontend systems. • Strong programming skills and CS fundamentals, with mastery in at least one backend language (Java, Python, etc., preference: Java and Spring Boot) and modern frontend frameworks (React, Angular, TypeScript). • Proven experience designing and evolving large-scale distributed systems and microservice architectures. • Demonstrated ability to own technical domains, making architectural trade-offs and long-term design decisions. • Experience driving cross-domain initiatives, coordinating with multiple teams to deliver cohesive solutions. • Track record of mentoring engineers, leading technical discussions, and influencing outcomes at an organizational level. • Experience with cloud platforms (AWS preferred), CI/CD pipelines, and modern DevOps practices. • Passion for solving complex problems, continuously learning, and delivering customer-focused innovations. • Excellent communication skills with the ability to influence technical and non-technical stakeholders alike.
